FAQs

Low and trace concentrations of organics and non-biodegradable organics.

The system is modular in nature, meaning that more modules can be installed to cope with changes in regulation, to tackle emerging contaminants or increases in manufacturing capabilities. There is not a minimum or maximum flow rate.

The system can be stored freestanding, skid-mounted or incorporated into concrete basins and can also be containerised for storage outdoors.

As the COD concentration of water increases, the amount of energy required for adsorbent regeneration increases. The process is most cost effective for low concentrations of organics.

Nyex™ media will undergo some minor physical attrition due to electrochemical damage over time and will therefore need ‘topping-up’ by around 2-4% per year on average. Operating at lower current densities will minimise this. Adsorbent attrition can also occur due to excessive backwashing so it is advised to operate with low solids to preserve the Nyex™ media.

Increased salt will increase the conductivity of the water. This results in a reduction in the voltage required, which lowers operational costs. The Nyex™ system has been tested on streams of up to 15% sodium chloride.

Effluent refers to an outflow of used water from a structure such as an industrial facility or sewage system. Industrial effluents can be treated onsite and reused, pre-treated and sent to the sewer or sent directly to the sewer for sewage treatment. For the latter, the facilities must pay a premium to the utilities provider to treat their effluent, which is known as a trade effluent charge. In terms of domestic effluent, this does not often require onsite treatment or carry any additional charge as the contamination level is not as high as industrial effluent, so effluent treatment is much simpler to achieve.

Wastewater refers to water which has been used and its original quality affected. Wastewater often contains contamination which must be removed to restore the water to its original state. Different types of wastewater require varying combinations of treatment processes to make the used water suitable for its intended purpose. Municipal wastewater which has been through primary and secondary treatment stages can be treated to advanced levels by tertiary technologies. These technologies remove residual contaminants such as organic and inorganic chemicals, metals, nitrogen and phosphorus.

Sewage refers to used water which also contains excrement and once it is directed to the sewer, it is known as sewer water. This sewer water is directed to a sewage treatment works and is managed as municipal wastewater effluent.

Water treatment companies manage effluent directed to the local sewer. This effluent ends up in the effluent treatment plant where it goes through various treatment steps to remove solids, contaminants and bacteria before it is directed back to the environment.

All wastewater which is created onsite at a business and directed to the sewer, not including domestic sewage, is known as trade effluent. Trade effluent discharge of industrial wastewater carries different charges dependent on its contents and must be agreed by the utilities provider prior to them providing wastewater treatment. Often this means that industrial wastewater analysis must be carried out. Effluents vary dependent on the industry and process the water has been through. Therefore pharmaceutical, textile industry wastewater (dying clothes), chemical wastewater and other industrial wastewaters will be monitored and charged differently. Trade effluent services providing industrial wastewater treatment are important to prevent negative impacts on human health and effects of environmental pollution.

Water treatment companies are responsible for sewage treatment at the local wastewater treatment plant. The wastewater treatment process involves various stages of water treatment involving wastewater solutions responsible for removing solids, chemicals and bacteria. Effluent undertakes these water treatment process steps in order to make it safe to return to the environment again.
