The purpose of wastewater treatment is to dispose off human and industrial effluents back into the natural environment without causing undue damage or posing health hazards. The process of wastewater treatment involves physical, chemical and biological processes that aim to improve the quality of the wastewater released in the environment. There are three levels of wastewater treatment, namely primary, secondary and advanced.
Primary wastewater treatment is designed to separate the solid, suspended and floating objects in the raw sewage. It includes a preliminary process of screening the raw sewage to trap suspended particles as well as sedimentation to remove the solid particles.
Secondary wastewater treatment involves biological processes that aim to remove organic matter dissolved in the sewage with the help of microbes that consume it for their own growth. Additional sedimentation process in settling tanks may also be carried out to remove the sludge from the sewage at this stage.
Advanced or tertiary wastewater treatment tries to remove all the impurities from the wastewater to produce almost drinking quality effluents. However, this is an expensive process requiring high level technical expertise, resources and machinery.
Finally, disinfection of the treated wastewater may be carried out to destroy harmful bacteria and other organisms that may still be present in wastewater.
Wastewater treatment is a huge business opportunity. Municipalities and local government authorities that manage the city water systems are constantly on the lookout for service providers that undertake wastewater treatment processes. Generally, Water treatment contracts are posted by water utilities advertising water treatment-related jobs and service providers with the relevant expertise bid for it. Finding water treatment bidding opportunities is now extremely easy using online resources.
New Desalination Bidding Opportunities
Desalination is a process where seawater is converted into fresh, drinking water by removing the salts and other harmful substances. In places where there is scarcity of potable water, desalination is undertaken. Desalination can be done with a process called ‘Reverse Osmosis’. In reverse osmosis, the water is filtered for impurities and salts by passing it over a series of membranes.
New desalination bidding opportunities are available online, just like those for wastewater treatment and purification. H2bid.com is one of the leading online resources that you (water utilities) can use to post a project.
Service providers with the technical expertise in this area of the water business can simply log on to H2bid.com and search for bidding opportunities corresponding to their line of work. They can get detailed information about such projects and bid for suitable ones. Members at the portal can even bid online if the utility company has opted for the e-bidding process.
H2bid.com is a useful resource that brings together service providers and Water treatment project companies in the water industry. Check out the site if you need to know about the latest water treatment and new desalination bidding opportunities available.
