Wet well cleaning and odour management using Actizyme Liquid G

The problem(s)

  1. Over a period of time, wet wells will slowly build up a film of Fats, Oils and Greases (FOG) over the walls and other infrastructure.

  2. The pressure main that removes the wastewater can also suffer from chokes and blockages.

  3. The water may contain dissolved FOG and “bad” bacteria that produces a lot of odour.

  4. The FOG in the wet well cause pungent odours and hence complaints from nearby residents.

  5. Historically, strong alkaline chemicals are used to treat the build up of FOG, but these can be dangerous, toxic and will kill any “good” bacteria. The other alternative is to use large amounts of water from a high pressure hose to clean the infrastructure.

The solution

There is a simple, environmentally friendly solution, that will reduce cleaning costs, extend the life of the infrastructure and remove offensive odours.

Our solution controls the build up of Fats, Oils and Greases (FOG), improves water quality, and controls odours, in a pressure station or Wet well. The introduction of Actizyme Liquid G means that it also begins to treat the water, before it reaches the main treatment plant.

Our solution does this by mixing mains pressure water with Actizyme Liquid G and spraying this over the inside of the well at regular intervals (typically every 15 minutes). Actizyme Liquid G liquid formulation contains natural bacteria, biodegradable surfactants and odour neutralizing fragrance.

Our solution will soften and dissolve, the FOG and Biofilms in the wet well by continually dosing with Actizyme Liquid G. By reducing the FOG deposits, cleaning time, odours and sulphide gases are greatly reduced.

Additionally, by introducing naturally occurring bacteria at strategic locations into the effluent collection systems, we can eliminate the wastewater FOG deposits, on rising mains walls, pumps and other parts of the infrastructure.

The component hardware

Our solution consists of three main parts:

1. Actizyme Liquid G Spray System Cabinet

The spray control system can either be mounted to the building wall or housed in a weatherproof, powder-coated aluminium security cabinet. This system will require connection to the council mains water supply and a 240v outlet.

To introduce the Actizyme Liquid G we attach a simple bracket to the side wall of the spray station. A spray arm neatly slots into this bracket, and allows an irrigation spray head to be supported, to spray the mixture of water and Liquid G throughout the wet well. Our solution utilises the site mains water to transport our Actizyme Liquid G to the spray head.  The spray head is  chosen to deliver the optimum amount of Actizyme Liquid G at an economical rate over a wide contact area.

3. Actizyme Liquid G Spray System Control Board

Our spray system control board ensures that Actizyme Liquid G is delivered using mains pressure water at regular intervals.

The control board comprises primarily of a 240v programmable logic controller, a metered dosing pump and a solenoid valve. There is a simple gate valve, a pressure control valve & pressure meter, a non-return valve and a simple manifold to inject the Actizyme Liquid G into the mains water. The control circuit is mounted to a non-metallic base board.
