Domestic Wastewater Applications on Environmental XPRT

Towns wastewater treatment

Towns wastewater, including water generated by domestic use, by shops, public cleaning and storm runoff, must be adequately treated to meet the discharge requirements of public channel, or reuse as irrigation water mainly.

Grease removing in wastewater pipes

Whether a collection system is handling domestic, commercial, or industrial waste; grease accumulation causes problems in wet wells, lift stations and pipelines. Problems with grease include interference with wet well level controls, reduced wet well capacity, plugging of pipes and pumps, and unsafe working conditions.

Recycling of plastic waste

Recyclable plastics can come from a large range of sources. Shredder residues containing plastics are typically coming from small domestic appliances, electrical and electronic equipment and cars. These materials each have their own difficulties when they have to be processed to recover clean plastics. With the GRS equipment we are able to handle each type of these materials.

Residential Areas and Hostelries wastewater treatment

Residential Areas and Hostelries wastewater, including water generated by domestic use, by shops, restaurants and laundries, must be adequately treated to meet the discharge requirements of public sewers or channel, or reuse as irrigation water mainly.

This wastewater has the following characteristics:

Variations in flow depending on the time of day and season (mainly in tourist areas).
High suspended solids content.
Presence of oils, fats and detergents.
High concentration of easily biodegradable organic matter.
Adequate concentration of nutrients.

Wastewater treatment for the tourism industry

The tourism sector lives by offering cleanliness and a comfortable environment. All guests love amenities such as pools, swimming ponds and parks, but they require high maintenance. Moreover, hotels produce domestic wastewaters as well. DAS Environmental Expert offers complete solutions for biological wastewater treatment for hotels and resorts.

Wastewater treatment solutions for anaerobic sludge digestion sector

Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen, used for industrial or domestic purposes to manage waste and/or to release energy. It is widely used as part of the process to treat wastewater, like Upflow Anaerobic Sludge Blanket (UASB) reactors. As part of an integrated waste management system, anaerobic digestion reduces the emission of landfill gas into the atmosphere. Anaerobic digestion is widely used as a renewable energy source because the process produces a methane and carbon dioxide rich biogas suitable for energy production, helping to replace fossil fuels. The nutrient-rich digestate which is also produced can be used as fertilizer. The digestion process begins with bacterial hydrolysis of the input materials in order to break down insoluble organic polymers such as carbohydrates and make them available for other bacteria. Acidogenic bacteria then convert the sugars and amino acids into carbon dioxide, hydrogen, ammonia, and organic acids. Acetogenic bacteria then convert these resulting organic acids into acetic acid, along with additional ammonia, hydrogen, and carbon dioxide. Finally, methanogens convert these products to methane and carbon dioxide.

Organic Micro-Pollutants Removal

Organic Micro-pollutants are low and trace levels of synthetic organic substances released in water through human activity. They can be found in industrial, agricultural and domestic wastewater streams. Some of the most difficult-to-treat wastewater contains micro-pollutants such as persistent organic pollutants (POPs), herbicides and pesticides, personal care products (PCPs), toxic chemicals, carcinogenic and endocrine disruptive compounds (EDCs), and emerging contaminants.

Filtration solutions for on-site treatment industry

Filter beds with pre-filter are simple, efficient and environmentally friendly ways of treating domestic wastewater from detached houses and holiday homes. The requirements related to operation and maintenance are few in relation to traditional compact plants. These systems can also be adapted to suit clusters of houses, schools, kindergartens, small companies etc.

Water treatment systems for chemical industry

The effluents that accrue in the cleaning process of silo vehicles and containers for transportation of raw materials for the chemical industry, are highly complex and constantly changing in the composition of wastewater. Flocculation as the prior art of treatment for chemical waste water can not remove many of the completely dissolved invisible substances. Thus, the residual stresses are evident despite high claritv of the `Treated effluent` is often well above the levels witch are applicable for wastewater in domestic environments.
