Projecting and implementing water, sewage, and effluent treatment and reuse plants

estações de tratamento de água, esgoto ou efluentes para reúso

Sharewater designs several kinds of water, sewage, and effluent treatment plants, focusing both on utilization or reuse and on water quality adjustment for disposal in collection networks or bodies of water. Its projects contemplate both new stations and retrofitted stations, being developed using advanced simulation and sizing tools, as well as 3D modeling tools, encompassing all necessary hydraulic and electric subsystems.

Implementation of these treatment plants can be done through several different contract models:

  • Consulting, basic or executive conception projects, and worksite monitoring.
  • Turn-key solutions including not only projects, but also plant execution and commissioning, delivering a ready-to-use system for the client.
  • B.O.T. (build, operate, and transfer) regimes, in which Sharewater covers all necessary investment for project, execution, and operation, and the client must only provide the necessary space for the treatment plant and pay for its operation proportionally to the volume of water treated.

Sewage treatment plants

A sewage treatment plant is suitable for adjustment of effluent quality for disposal or for water reuse. Reuse is especially helpful in avoiding unnecessary expenses both through substitution of drinking water in processes that do not require it and in lowering disposal of sewage into collection networks, which leads to higher water and sewage bills. Sewage treatment and reuse plants are indicated to enterprises with high and constant sewage generation and with high consumption of water in processes that do not require drinking water, such as flushing, irrigation, washing floors, air conditioning systems, and several industrial processes, to name a few.

Grey water treatment plants

A grey water treatment and reuse plant bring benefits similar to those brought by a sewage treatment plant. Its particularity lies in collecting sewage only from sources that do not include effluents from toilets and kitchen sinks, lowering the effluent’s organic load and thus allowing for the adoption of simpler treatment processes with lower cost when compared to sewage treatment processes. This is recommended for enterprises aiming to enjoy the benefits of water reuse with smaller initial investment and greater operational ease.

Industrial effluents and diversified treatment plants

Different contaminated water samples have specific chemical composition and contaminant loads, demanding customized treatment processes. Sharewater conducts treatability studies and designs treatment plants with personalized process sequences defined by each kind of effluent, both for quality adjustment for disposal and for reuse.

Rainwater harvesting systems

Rainwater harvesting systems are an excellent opportunity for reducing consumption of drinking water. These systems have relatively low costs and are indicated to enterprises with large roof areas and high consumption of water in processes that do not require drinking water, such as flushing, irrigation, washing floors, air conditioning systems, and several industrial processes, to name a few.

Implementation of rainwater harvesting systems developed by Sharewater has an especially low cost due to the optimization of reservoir dimensions (one of the most commonly expensive elements of system implementation) through a methodology developed internally, which uses a computer simulation of the system to determine optimal volume and optimal catchment area, which translates to better return on your investment.

Surface and groundwater treatment plants

Substituting drinking water from the water utilities is advantageous as well, since it tends to be more expensive than other drinking water sources. Not only that, but certain enterprises simply cannot count on public water and sewage services.

Sharewater projects surface water (rivers and lakes) and groundwater treatment plants both for drinking or general purposes. Through partnerships it has cultivated throughout the years, it also acts in drilling wells and executing water courses catchment systems.

Leachate treatment plants

The result of the degradation of organic waste components from landfills is called leachate. It is a hazardous waste to the environment, due to its low biodegradability, its toxic organic compounds high loads and, as a result, it contaminates groundwater and causes public health problems. The technology currently employed in leachate treatment systems is not efficient and presents a continuous increase of contaminants in the landfill, only increasing environmental damages.

Sharewater has promoted studies in this area and developed new technologies, obtaining high quality of treated effluent, high treatment capacity and low waste generation.
