Water treatment is a complex procedure uniquely adapted to various water types and therefore requires wide know how and expertise
Increasing environmental awareness has resulted in stringent regulatory demands for water quality thereby increasing water treatment related charges
Water treatment is a complex procedure uniquely adapted to various water types and therefore requires wide know how and expertise
Planning and constructing water treatment facilities is usually performed over long periods of time and is spread over large areas. When severe water pollution occurs one needs immediate treatment in limited areas
Arrow experts, together with our vast investment in new technologies, have gained the capability to handle a very wide range of requirements involving different methods, applications and regulations
Arrow technologies address various contaminations such as metals, nitrates suspended solids, complex organic compounds, dissolved salts, THMs, toxins and more
The recycled water is adapted to customer’s demands for re-use of various processes
Arrow offer a reliable, effective, economic and sustainable solution
Arrow treats and recycles water for re-use by compact facilities, both stationary and mobile, built to exact client specifications

Pre-treatment
» Initial treatment process to improve water quality supplied from various sources, for example: river water, well water, reservoir water etc.
» Process and technologies include the following steps:
› Coagulation and Flocculation (use of chemicals to improve the filtration process downstream).
› Softening (by antiscalant or resins)
› Filtration tanks (filtration under press) containing various media such as basalt, sand, anthracite.
› Clarifiers
› Flotation
› Activated carbon removal such as organic substances and fats.
Filtration
» Mechanical screening filter press.
» Media filtration using different sand types, quartz & anthracite, catalytic media and gravity filters.
» Basic filtration using depth filters and cartridge filters.
High quality filtration
» Through a UF (Ultra Filtration) type membrane for up to 0.02 microns filtration
Membrane processing
» Nano Filtration (NF)
» Submersible Membranes
» Membranes Bio-Reactor (MBR)
Reverse Osmosis (RO) and Desalination (mobile skid)
» Process of removing salts and various ions for producing mineral free water.
Polishing technology
Advanced polishing technology to create ultra-pure water quality by:\
» Resin
» Mixed bed (Ion exchange)
» Electrodeionization (EDI)
» Electrodialysis Reversal (EDR)
Advanced treatment
Oxidation treatment which includes the use of advanced technology in order to create free radicals able to break the molecule bonds.
Oil & gas
Mining and quarry
