Description of Treatment System

Primary
The first stage of treatment is to separate the solids from the liquids, solids remain in this first chamber where an anaerobic digestion process takes place. The digestion is accelerated by the presence of anaerobic micro-organisms which multiply rapidly under ideal conditions and that will ensure that the offensive faecal solids are turned into an inert waste.

Flow Regulation
The System can be designed to regulate the flow of wastewater influent for consistent treatment. Eliminating surge flows reduces the cost and size of the biological treatment process. Flow balancing is achieved by means of exact inlet and outlet flow holes heights controlling the entire surface area of tanks, with discharge pumps dispersing the treatment waste at the final stage at a constant flow rate.

Aeration/Contact Filtration
Treatment liquids flow into the aeration chambers where the liquid is aerated by means of a submerged diffused system with either one or two blowers with the appropriate capacity to generate air at the desired litres per minute rate. The water is circulated periodically through and over contact media that has a large surface area to volume ratio.
The media sustains the growth of an attached bio-mass that remains stationary encouraging either slow growing of slow multiplying nitrifying bacteria to develop.

Sedimentation/Clarifier
Following aeration, the effluent is allowed to settle under quiescent conditions in the clarification chamber. Settled solids are periodically pumped back to the first chamber via a venturi system activated by the litres per minute blowers.

U.V. Disinfection/Pump Chamber
Supernatant effluent from the sedimentation contains coliform and other noxious bacteria including some viruses. Ultra-violet light or chlorination may be used in the disinfection process. Two pumps will be installed, one acting as an emergency backup with separate alarms. The disinfected water will be pumped through an underground main irrigation line to an irrigation network or storage facility.
