Many effluent streams need to achieve high solids removal capacity for either reusing the water or in order to meet string effluent discharge regulations. The AquaHD solution can be a suitable for as a stand-alone solution for solids removal or as solids removal step in a larger wastewater treatment plant.
In wastewater treatment plants, the aquaHD solution is installed as a compact and cost-efficient solution to clarifiers. The AquaHD system had been successfully installed either in new or to upgrade existing clarifiers in wastewater treatment plants.
SURFACE WATER TREATMENT
Surface water treatment facilities face the challenge of producing high-quality clean water for drinking, agricultural or industrial applications, regardless of fluctuating turbidity and TSS (Total Suspended Solids) inlet conditions. In order to meet the increasing demand for high quality and continuous supply of water, many water treatment plants will incorporate a solid separation step. This step will be needed either as a pretreatment or a stand-alone process if turbidity levels exceed 50 - 100 NTU, or for the treatment of fine particles.
Installing the efficient AquaHD system, which is able to handle variations in turbidity, allows the supply of clean and safe water from any water source.
Algae removal poses one serious challenge for any solids separation process. Traditionally, most solids separation processes are being done by separation that is dependent on the density difference between the water and the particles. Since algae are generally small and have low density difference from the water, gravity separation is relatively less efficient when considering algae separation process. Therefore, algae removal is typically being done by using high velocity centrifuges or by Dissolved Air flotation (DAF). However, these processes are expensive and consume large amount of energy.
Due to the Natica’s unique structure, it can remove a wide range of suspended solids as small as 2 microns from water with dirt load of up to 4000 PPM of TSS.
With the move to better and more precise agriculture production, the need for a higher quality of water at the inlet to the irrigation systems and to the processing line is increasing. However, such high-quality water is often unavailable and therefore the source water needs to be treated well.
One of the main impurities that needs to be removed before use in irrigation systems is particles that are present in the water. As well as clogging the irrigation piping, high solids content might require frequent replacement of the whole irrigation system. This inevitably resulted in high maintenance costs and long downtimes in production.
The Natica system can effectively treat water for fine particles removal and is capable of maintaining water quality at the inlet to the irrigation below 20 NTU (over 95% removal).
