In some regions of the world, people cannot reach freshwater easily. So they have to recycle used water and maybe wastewater. water treatment engineering companies are taking care of more and more water reuse technologies.
Water recycling, or water reuse, is reusing treated wastewater for purposes where there is no direct human contact, such as irrigation, toilets, and replenishing groundwater sources.
Gray water is a type of reusable wastewater that comes from residential and commercial bathrooms (sinks and bathtubs) and washing machines. Due to increasing dry weather/ no rain conditions, municipalities are finding new ways to use treated wastewater for street cleanings, watering golf courses, and landscaping. Treated wastewater is becoming more of a resource rather than just sewage.
Refinery water treatment application can use a reuse system, so refinery water treatment plant needs this kind of technology.
SOLUTIONS
Membrane Biological Reactors:

There are two types of MBR technologies:
(a) external MBR (MBR) in which the membrane modules are placed outside the bioreactor (MT only)
(b) submerged MBR (sMBR) where the membrane module is placed inside the bioreactor (FS and
HF). The types of membranes used in MBRs are:
(i) flat sheet (FS), (ii) hollow fiber (HF), and multitube (MT).

Submerged membrane bioreactor (MBR) technology employing MF/UF membranes is being used increasingly for biological wastewater treatments. Biological wastewater treatment is used to remove all organic and nitrogen-containing substances by anaerobic or aerobic conversion. Water treatment in the pharmaceutical industry can use this technology. Conventional wastewater treatment is composed of two reactors: an aerated and a non-aerated reactor. In the MBR process, the biological reactor is integrated with the immersed membrane unit, which is placed in the nitrification area. The air sparged along the membrane surface creates turbulence at the membrane surface, cleaning or scrubbing it. water treatment engineering companies are using membrane bioreactors and membrane bioreactors are able to remove more than 95% of the chemical oxygen demand (COD) while the reduction of biological oxygen demand (BOD) is even higher.

Polymeric MF membranes with a pore size of 0.1–0.4 μm are the main membranes used in sMBR systems while tubular inorganic membranes are generally used in eMBR units by water treatment engineering companies. The MBR units are preferred to sMBR units when treating concentrated effluents or concentrated biomass to avoid membrane fouling by water treatment engineering companies; a higher shear rate is achieved with a higher recycle flow rate.

A key area of process deficiency is fouling by microorganisms as a result of microbial products, concentration, and size of particles. In addition, there is concern about whether oxygen can become the limiting factor during aerobic biological activity. The other method for water reuse is the reverse osmosis system, refinery water treatment applications also can use reverse osmosis technology. If you need refinery water treatment, you are at the correct address.
We have also other solutions for water treatment in the pharmaceutical industry, you can check our 2-stage RO system, and EDI system. Especially Electrodeionization becomes a more popular process for water treatment in the pharmaceutical industry.

Water reuse (also commonly known as water recycling or water reclamation) reclaims water from different of sources then treats and reuses it for beneficial purposes such as agriculture and irrigation, potable water supplies, groundwater replenishment, industrial processes, and environmental restoration.

Water treatment engineering companies use MBR technologies for water treatment in the pharmaceutical industry, refinery water treatment, and waste water treatment applications. Water treatment in the pharmaceutical industry also uses an Ultrafiltration system for water reuse.
