Commercial Wastewater Treatment

Biocell commercial sewage treatment systems

Many commercial developments are located in areas where there is no main public sewer available. In these instances, commercial off mains drainage solutions are required.

In the past, commercial off mains drainage options were very limited in their scope. Septic tanks were often used. Septic tanks however, have a very limited treatment efficiency, as low as 20%. Poor quality effluent can result in pollution of groundwater and surface waters. Also, the poor suspended solid removal rates can cause soakaways and percolation areas to fail.

An alternative method for commercial sewage and wastewater management was in the form of a cesspit or a cesspool. These wastewater storage tanks are designed to hold wastewater and sewage. They are them emptied intermittently by a licensed waste collection company using a vacuum tanker. While cesspits are effective, the regular desludging and emptying is very expensive and unsustainable.

Commercial developments such as hotels, leisure centres, caravan parks, nursing homes and schools now install commercial sewage treatment plants to deal with the sewage generated onsite. A number of different treatment processes are available, including activated sludge systems, SAF systems [submerged aerated filter], MBBR [moving bed biological reactor] and SBR systems [sequential batch reactor]. RBC [rotating biological contactor] is also an option, but they are less favored due to the high maintenance and operational costs.

Commercial sewage treatment plants are available for both above and below ground applications. Systems are offered in reinforced precast concrete tanks, GRP tanks and plastic tanks. With most commercial sewage treatment plants, it is important to have a grease trap installed to remove fats, oils and grease from the sewage and wastewater, as this can have a negative impact on the treatment process.

Biocell  commercial sewage treatment plants can be installed to achieve any level of effluent required. Our systems are reliable, robust, and they have the lowest energy and maintenance costs on the market.
