RO Filtration Plant
Nawa provides full service installation, maintenance, repair and replacement parts for industrial and commercial water treatment systems.
Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove ions, molecules and larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property, that is driven by chemical potential differences of the solvent, a thermodynamic parameter. Reverse osmosis can remove many types of dissolved and suspended species from water, including bacteria, and is used in both industrial processes and the production of potable water.
NAWA offers preventative maintenance agreements to ensure that your Reverse Osmosis and pre/post treatment systems are functioning at peak performance. An experienced engineer can work with you to develop a customized preventative maintenance schedule that is designed specifically for your water treatment system.

Demi Water Plant
Demineralized water or demi water is water of which the minerals or salts are removed. It is used in applications where water with low salt content or low conductivity is required.

Biogas refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas is a renewable energy source/
A biogas plant is the name often given to an anaerobic digester that treats farm wastes or energy crops. It can be produced using anaerobic digesters (air-tight tanks with different configurations). These plants can be fed with energy crops such as maize silage or biodegradable wastes including sewage sludge and food waste. During the process, the micro-organisms transform biomass waste into biogas (mainly methane and carbon dioxide) and digestate.
Double Membrane Biogas Storage Tank /Gas holder
The Double Membrane Gasholder is used for any application that needs gas storage such as municipal wastewater treatment plants with anaerobic digestion, landfills with biogas usage, industrial wastewater treatment plants, agricultural energy recovery facilities, etc.
Custom-Made Biogas Storage For Wastewater Treatment Plants and Energy Recovery Facilities — The BETTER double membrane gasholder may be mounted on the ground typically in the form of a ¾ sphere, or mounted on the top of an anaerobic digester or tank functioning as a durable tank cover and storage vessel.
Double Membrane Biogas Holders – How do they work?
The Advantages of this construction are
• Simple maintenance free operation
• Easy mounting in only a few days
• Long Life expectancy
The double membrane biogas storage tank system consists of an external membrane which forms the visible outer round contour of the tank, an internal membrane and a bottom membrane which encloses the actual gas space.
A pair of duty and standby blowers provides air to the space between inner and outer membranes to regulate the variation in gas input and gas output, thus keeping the gas pressure inside the tank at a constant level, it also keeps the external membrane rigid protecting it against weather elements.
The supporting air in the space between the inner and outer membranes is balanced with the addition of an air damper valve. As volume of the gas space changes according to the quantity of gas flowing in and out of the tank, a level detection device measures the volume of the inner membrane and relays the information to the control panel to regulate the operation of the plant. The gas supply and discharge pipes are cast into the concrete foundations before the actual erection of the tank and then hermetically sealed to the bottom membrane on installation. The double membrane biogas storage tank is then clamped to the concrete foundation by means of an anchor ring.
