10nrOur “ULTRA VIOLET DISINFECTION PROCESS”, ensures complete disinfection.

Description of Treatment System

To the right is a general view of 10NR

Primary 1 (Anaerobic digestion)

Digestion of solids by Anaerobic Digestion.

Primary 2 (Anaerobic filtration)

Further digestion of solids passing through our unique primary filter media before flowing to Aeration chamber.

Aeration / Contact Filtration

Filtered effluent from the primary chamber flow into the Aeration chamber where the liquid is aerated by means of a submerged diffuser system connected to a blower with a specific litres of air per minute. The water is circulated around and through the contact media that has large surface area to volume ratio. The media sustains the growth of an attached biomass, remaining stationary encouraging either slow growing or 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 primary chamber via a venturi system.

Disinfection / Holding Chamber

Supernatant effluent from the sedimentation contains coliform and other noxious bacteria with the possibility of viruses. Our advanced Technology of implementing our “ULTRA VIOLET DISINFECTION PROCESS”, ensures complete disinfection and minimizes costly maintenance problems associated with all chlorinated systems where the oxidation effects from the chlorine prevail causing costly repairs to structural and mechanical parts of the system.

Irrigation

The disinfected water will then be irrigated to a non-recreational irrigation area. A suitable area for irrigation should be allowed for, size of this area dependent on size of dwelling and number of bedrooms. A geo-technical report can also assist in sizing the irrigation/disposal area.

Tank P74 FlowWe have used technology from waste water treatment systems.

ENVIROCYCLE Pump to Rising Main Sewer P74

The Envirocycle P74 wastewater treatment system is a pump to sewer tank for special areas not suited for continual discharge on to block, these reasons could be high water table, shallow rock shelf and subdivision's which would have its own grid pattern of sewer pipes running toward the local town sewer with pipe lines only 65mm in diameter.

We have used technology from waste water treatment systems to bring to you, the customer, a pump to sewer unit that has capacity to handle waste for 3 to 6 bedroom homes.

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.

How it Works

During the ULTRAVIOLET DISINFECTION PROCESS water passes through a field of concentrated short-wave Ultraviolet energy thousands of times more powerful than sunlight.

What is Disinfection?

Ultraviolet light is a particular selection of wavelengths from the light spectrum that occurs naturally in sunlight. It damages the DNA molecules in bacteria, viruses and other micro-organisms preventing them from replicating and surviving to cause harm.

During the ULTRAVIOLET DISINFECTION PROCESS water passes through a field of concentrated short-wave ultraviolet energy thousands of time more powerful than sunlight. Any living micro-organisms are quickly destroyed, providing clean healthy water.

Some typical micro-organisms killed by ultraviolet disinfection include cholera, dysentery, hepatitis, typhoid and E-Coli.
