Protecting public health and the environment is not the only purpose of civil (or municipal) wastewater treatment: in fact, the issue of reuse of the blue resource is increasingly felt by communities. A wastewater with low levels of suspended solids exiting the tertiary stage is one of the key conditions for reuse: MITA can support engineering offices and contractors with state-of-the-art filtration solutions.
Organic and chemical substances, oils and greases, suspended solids in different amounts-all these agents contribute to the pollution of “civil wastewater” , or “municipal water,” by which we denote the wastewater produced by all domestic activities of human beings. The sources of this pollution can thus be residential homes, offices, stores and other urban settlements.
The main purpose of civil wastewater treatment is, of course, to protect public health and the environment, but it is not the only one: in recent years, as a result of major climate changes and increasingly complex resource management, the reuse of treated water for civil, industrial, and irrigation purposes is becoming increasingly popular.
Civil wastewater is categorized as opposed to industrial wastewater mainly because of its different management: while the latter differs considerably from plant to plant in terms of the quality and quantity of the effluent, the former is treated in civil wastewater treatment plants (WWTPs) through a very specific series of steps, regulated by local laws. The aim is to remove all the types of pollutants that can arrive from an entire community, whose effluent production is measured in population equivalents: there are sewage treatment plants of tens or hundreds of population equivalents, whose water is invariably treated through primary (roughing), secondary (biological) and tertiary (finishing), disinfection (by potabilization) treatments.
Primary, secondary and tertiary treatments, pretreatment and disinfection: these are terms, corresponding to as many stages of depollution, that are always encountered when we talk about water purification plants in the civil sector.
We can summarize them as follows.
Engineering firms, consultants, and contractors can seek support from MITA Water Technologies in the three main stages of civil wastewater treatments.
We are also aware of how much our stakeholders need ongoing, pre- and post-installation support, so we offer services for the entire product life cycle. These include bench and field pilot testing, system upgrading and expansion, maintenance and spare parts.
Efficiency and sustainability in process water reuse: this has always been the focus of a Vietnamese plant of a multinational beverage company, which now optimizes the process with MITA pile cloth filters: reduced performance and power consumption.
