Design
Biotec sewage treatment plants are available as standard or high level nitrification plants. They employ a development of the well-proven aerobic biological process for the purification of sewage and waste water.
This process takes place in four distinct stages:-
- Primary Screening and Settlement
This is the initial stage of treatment and simply involves the retention of coarse solids present in raw sewage and waste water for subsequent gradual breakdown.
- Carbonaceous Biological Treatment
Substantial BOD reduction takes place here, where the carbonaceous pollutants are removed by presenting the sewage to the micro-organisms in the presence of oxygen. The treatment is achieved by continually distributing the screened liquids over the biological media.
- Nitrifying Biological Treatment
Additional treatment is provided in order to reduce the Ammoniacal Nitrogen. There are two levels of Nitrification available. For most applications the standard is suitable. However, for particularly sensitive applications the high level unit can be selected.
- Final Settlement
A natural by-product of biological treatment is humus sludge and this is separated for further treatment. The treated effluent is discharged via the outlet. Under normal domestic conditions 20mg/I BOD, 30mg/I SS, 20mg/I Ammonia can be achieved with standard plants and 10mg/I Ammonia can be achieved with high rate plants.
Installation
The unit is normally installed with the cover flush, however it can protrude above ground if required by site levels.
Siting should be no closer than 15m from the nearest house. The plant should be seated on a concrete base with a surround of pea shingle in a dry site or concrete in a wet site.
The blower housing can be located anywhere within a 15m radius of the plant itself.
Maintenance
Biotec sewage treatment plants are designed for minimum low cost maintenance.
Titan offers a full commissioning and after sales service involving planned maintenance visits.
Under normal usage the plant will require periodic emptying to prevent excessive build up of surplus sludge.
Options
Pumpsets - where the treated effluent has to be dispersed to a higher area because of site levels or ground water.
Sample Chambers - for accurate and convenient effluent sampling, as required by the Environment Agency.
Alarm Systems - for the warning of power or equipment failure.
Advice
The information in this sales literature is by necessity brief. For more detailed technical literature and drawings regarding applications, installation, maintenance or specific options, please contact Titan. We have both internal and field sales staf who will be pleased to assist you.
Legal Requirements
Prior to installation, there is a legal requirement to obtain a Consent to Discharge from the Environment Agency. Titan offer full assistance in this respect.
