ACT WISY 4 STEP RAINWATER HARVESTING SYSTEMS

AN INNOVATIVE IDEAS OF MODERN RAINWATER HARVESTING SYSTEMS - ACT WISY

ACT-WISY is an Indo - German trade name for the “Emerging / Modern technologies of Rainwater Harvesting Systems” as a total concept of water management for domestic and industrial applications.  We are introducing Rainwater Harvesting Filtration Systems in collaboration with WISY AG, German entity for RWHS over the last 25 years.

ACT-WISY 4 STEP RAINWATER HARVESTING FILTRATION METHODOLOGIES:

ACT-WISY’s filtration system works based on vertical and cylindrical type of filter with adhesion principle adopting the theory of natural flow of water. It has an automatic system of rinsing/cleaning by using 3 to 15 % of rainwater harvested. The filtered water will be collected to one side of the chamber and send to storage. The filtered water in the storage tank undergoes different stages of oxygenation to maintaining the water quality for longer storage duration. The rinsing/dirt water shall be sent to drain out or sewage.

Step 1: Filtration of rainwater by Down pipe filter or Vortex filter along with the oxygenation.

Harvested rainwater should be filtered and aerated before entering to the tank for storage. Filtration remove the debris and particles larger than 0.28 mm and are flushed out to the drain outlet or sewage.  ACT-WISY pre-tank filters can accomplishes  removal of the suspended solids along with oxygenation of the water, both of these task can assures the water quality in the tank for longer storage duration.

Step 2: Acceleration of sedimentation and distribution of oxygenated rainwater within the storage or open well.

This device is beneficial for the tank and may remove additional sediment from the water. The ACT-WISY smoothing inlet calms rainwater as it enters the storage tank to prevent the agitation of sediment at the rainwater inlet. The smoothing inlet also helps to aerate the harvested rainwater by directing the rainwater in upward and outward, avoiding any disruption of the water in the base of the tank and preserving water quality in the tank.

Step 3: Extraction of filtered water from the storage by a Floating filter.

For re-use, the water is extracted from the tank (10-15 cm from the top surface of water) by Floating Suction Filter, which ensures that the water taken is most oxygen enriched.

Step 4: Overflow control, skimming of floating substances.

To prevent the back flow to the storage during heavy rains, the storage tank includes an overflow protection device, called Multisiphon.

ACT WISY RAINWATER HARVESTING SYSTEM INSTALLATION at SAFALYAM COMPLEX

ACT-WISY RWHS INSTALLATION  at

 SAPHALYAM COMPLEX

We ACT-WISY, successfully installed our emerging / latest Systems of Rainwater Harvesting in SAPHALYAM COMPLEX, Palayam, Thiruvananthapuram under the proposal of TRIDA (Thiruvananthapuram Development Authority).

The ceremony was inaugurated by Hon'ble Minister for Health & Family welfare, V S Sivakumar at Saphalyam Complex on 28th October 2014. The minister said about the importance of rainwater harvesting systems and he conclude his words by "It is our duty to develop a culture of water harvesting". 

The inaugural ceremony was a great & successful event with presents of lot of dignitaries from various fields. The TRIDA Secretary, P Anil Kumar explained about the features & significance of the Rainwater Harvesting Systems installed in Saphalyam complex. He said that, RWHS should be promoted by each and every family and thereby to conserve the water for the future.

The Managing Director, Mr. Anzar Azad & The Technical Advisor of WISY AG Germany, Mr. Fritz Poerschke had taken the speech on regarding the awareness and importance of Rainwater Harvesting Systems in this modern era.

The case study :

Before Installation:

Saphalyam complex is a small commercial building having 5000 sq.ft catchment area. The rainwater falls in such an area was goes off to the drain or sewage because of improper water management and conservation technologies.

Saphalyam complex have no rainwater harvesting systems. There is a sump of having 350 CBM water storage capacities. Water is stored in the sump without any treatment or filtration, which cause bad quality of water.

The actual problems reported as follows:

•      No technologies or guidelines for harvesting the rainwater.
•      No filtration of water stored in the sump.
•      Accumulation of dirt in the sump.
•      Mixing up of sediments in the sump.
•      Water experiences foul smell.

After Installation:

ACT WISY proposed two stage filtration systems for Saphalyam Complex.

1.       Vortex Fine Filter WFF 150 for fine filtration.

2.     Smoothing Inlet for sedimentation & oxygenation of water within the storage.

The WFF 150 Vortex Filter is the only medium sized vertical filter for small commercial or large residential applications that provides the highest quality of rainwater. Because of the vertical design, the filter has a self-cleaning effect. Debris is discharged from the filter along with “first flush” and excess water necessary to carry debris to sewage. The filter provides the highest quality of stored rainwater with minimal maintenance.

Smoothing Inlet in the storage tank accelerates the sedimentation process and distributes the oxygenated filtered water. This preserves the highest quality of filtered water in the tank for longer storage duration.

After RWHS installation, Saphalyam complex have no water shortage problems. The building itself save the precious water from the nature and preserves that water with a good quality up to longer duration for their commercial needs.
