municipal wastewater treatmentOur solutions are specifically suited to applications such as:

  • Single houses
  • Small communities
  • Hotels
  • Schools
  • Gas stations
  • Tourism sites and campsites

The wastewater generated from each of the above referenced applications can vary significantly with regard to flows and loads generated. Hotels for example can have major fluctuations in wastewater loadings due to seasonal variations in visitor numbers. The wastewater generated can have higher BOD and COD than normal due to onsite catering and events. And the wastewater generated can have higher BOD and COD than normal due to onsite catering and events. Schools also have variable flows and loads, with no occupancy overnight or at weekends, and extended periods of non use with summer holidays. Gas stations and motorway service stations can have very high toilet usage, resulting in high ammonia levels in the wastewater.

Throughout the last 10 years we have acquired a lot of experience and with the outstanding technical abilities of our team we are a perfect choice for your project.

With globalisation, more people are travelling to spend their holidays in foreign countries. This has generated a boom in the hotel industry, where with more competition, owners and managers have to offer their customers exceptional service.

Every good hotel produces a huge amount of wastewater through their bar, kitchen, swimming pool, bathrooms, etc. Therefore it is absolutely necessary for it to have a reliable and good functioning wastewater treatment system that can handle the wastewater.

Wrongly located, installed and maintained septic tanks can lead to pollution of the environment, odour and nuisance, with irreversible damage to the image of your hotel as an end result.

Finding the right wastewater system for your hotel is key for optimal running system. Various factors like the size of your hotel and daily wastewater volumes (for on and off season) play a role in the system you should choose. For hotels we have a range of above and below ground electric and non electric solutions. We would be happy to assist you in finding the perfect sewage treatment plant for your hotel.

Gas station

oil and gas solution

It is a common issue for wastewater treatment plants at motorway service stations to be undersized or overloaded due to increasing traffic, greater numbers of visitors or expansion of the facilities. Additionally, stricter regulations on discharge licensing may warrant an upgrade to an existing treatment plant to meet new higher effluent standards. ClearFox®  can help identify the areas of concern and make recommendations for the best course of action.

We provide bespoke wastewater treatment solutions to suit any available space, above ground or below ground, and to any effluent standards. Where there is a compliance issue with the environment agency due to a breach of a discharge license or permit, we can offer an upgrade to ensure full compliance.

A combination of the use of kitchen, cleaning and washroom facilities produce the wastewater at a filling or gas station. It is characterized by highly variable flows, high ammonia content and high FOG content due to catering and food prep. There are various tried and tested methods for treating service station wastewater – the most suitable will depend on the unique requirements of the project itself. ClearFox® will engineer a solution to meet the exact project requirements.

ClearFox® has a proven track record in providing low cost, reliable sewage treatment plants for service stations using the latest developments in commercial wastewater treatment such as SBR and FBR  technology. This technology operates on a project specific pre-programmed treatment sequence, which is ideal for applications with variable flows, high ammonia content and high FOG.


wastewater treatment for Schools in Africa
SBR Retrofitting Kit

ClearFox® is specialized in the manufacture and design of plug and play modular solutions for school wastewater. Our products are low in energy consumption and are very cost-efficient. There is a minimal visual impact and special safety features are implemented especially for schools to make sure of a safe environment for kids. Our easy to install products can be installed within a short period of time during holidays, need little maintenance and are easy to operate for people without knowledge of wastewater plants.

As a contrast to a domestic household, there are sometimes thousands of pupils in a single school or college.

For the most part, sewage from buildings with educational purposes consists of a lot of toilet flushes and comparably lower amounts of organic loadings, thus leading to a higher concentration of ammonia. Most schools are on a tight budget,so it is important for their wastewater treatment plant to be cost efficient.

Schools do not operate during holidays and have the highest wastewater production during the morning until afternoon. Therefore, a product that adapts to the periods of high wastewater production and the low wastewater production during holidays is required.

Our ClearFox® professionals would advise to either get an SBR system or a containerized system.

ClearFox® is a market leader in the design, manufacture and supply of a range of innovations, cost effective wastewater treatment solutions for municipal wastewater.

We have successfully implemented solutions in many countries around the world for a range of project sizes. Our containerised solutions can be utilised to upgrade or replace an existing municipal wastewater treatment plant. We also offer SBR systems for new projects. We also offer ancillary products including sludge dewatering and mechanical pretreatment.

Containerised wastewater treatment modules are a proven method of fast, reliable and effective wastewater treatment for municipal wastewater treatment applications. They achieve a lower capex than constructing a wastewater treatment plant onsite using traditional civil engineering methods. Cntainerised FBBR systems and SBR systems are flexible wastewater and sewage treatment solutions that can be applied to a number of project types.

Capacity increase at existing wastewater treatment plant – Mobile containerised FBBR plants can be utilised to increase the treatment capacity of an existing wastewater treatment plant. The can also be added upstream of an existing sewage treatment plant to achieve a higher effluent standard where stricter compliance limits are being imposed. This is a fast solution that can be mobilised and installed onsite to deal with any wastewater treatment requirements.

Wastewater treatment plant upgrade – Many existing municipal wastewater treatment plants are currently overloaded and require upgrades to allow them to deal with extra hydraulic and organic loads they are receiving. The conventional upgrade route requires major civil works, large footprints and a long timeframe. In contract, the use of a  containerised FBR plant allows for the simple installation of wastewater treatment modules to increase the capacity. It is the rapid mobilisation and small footprint that make containerised wastewater treatment plants the ideal solution for municipal wastewater treatment system upgrades.

Bypass wastewater treatment – Temporary construction works on existing live sewage infrastructure can result in complications requiring the sewage and wastewater to be diverted and treated while construction work is ongoing. The use of temporary mobile FBBR plants whether purchased or leased allows water utilities and contractors to provide a method of wastewater treatment while aeration basins are isolated for construction activities.

Tourism applications such as caravan parks and campsites generate significant amounts of wastewater. Due to the location of caravan parks in rural and scenic areas, there can often be very strict compliance limits set for ammonia, phosphorus, nitrogen and BOD. This is often due to the fact that treated effluent is discharged into sensitive watercourses or estuaries. When it comes to off mains drainage solutions for caravan parks or campsites, these key factors need careful consideration. For this reason, it is important to seek specialist input at design stage.

Our packaged plants are the industry standard in both permanent and seasonal caravan parks and campsites. In addition to offering complete wastewater treatment plants to replace failing systems, we can also offer add-on modules for treating specific parameters such as ammonia. This can be of benefit when an existing system is in breach of the environment agency discharge consent.

We provide bespoke municipal wastewater treatment solutions to suit any available space, above ground or below ground, and to any effluent standards. Where there is a compliance issue with the environment agency due to a breach of a discharge license or permit, we can offer an upgrade to ensure full compliance.
