Our goal is to streamline and optimize the treatment and management of water resources for our clients ensuring the performance and water utilization are maximized.
The product manufacturing process and industries require a clean water source and per degree of process need for production, manufacturing, and many more allied uses. Water is required for nearly every step of production across a multitude of different industries. According to the product being manufactured and the raw water quality as per source, a special level of treatment technologies is provided. Quantity of water requirement also varies as per production and hence to meet quality with production cost selective line of treatment is considered.
Drinking water contains water molecules and a large variety of other substances. Being universal solvent other substances easily dissolves in water. Water that falls to earth during rain showers dissolves substances, particles, and gasses such as oxygen, which can be found in the air. Contaminants that are present in the air also dissolve in rainwater. When surface water flows on earth it also dissolves several different substances, such as sand particles, organic matter, microorganisms, and minerals. Water that settles into the ground and becomes groundwater, often contains large amounts of dissolved minerals, as a result of contact with soils and rocks. Human activities, such as agriculture and industrial waste, and sewer water discharge cause several pollutants to enter the water.

Ultra filtration System
Ultra filtration is a membrane-based technology to remove suspended solids, Colloidal matter, High Molecular Weight Substances, bacteria, and viruses from various feed water sources. UF can achieve a low and consistent silt density index (SDI) and is often used as a pre-treatment for reverse osmosis using surface water, seawater, and biologically treated wastewater as a feed source.
Ultra filtration (UF) is recognized as a low-pressure membrane filtration process, it is usually defined to be limited to membranes with pore diameters from 0.005µm to 0.1µm. When the source water is passing through the filter under a trans-membrane pressure provided by gravity or a pump, the suspended solids particles, bacteria and most viruses can be removed, and the use of chemicals, capital, and operating cost can be reduced.
Features
- Excellent permeate quality
- Product SDI typically less than 1

- Purification of surface and well water for portable applications
- Filtration of industrial water
- Zero liquid discharge recycle and reuse
Electro-Deionization
Electro Deionization is a process that de-ionizes water by means of applied current. Effectively removes dissolved inorganic matter. Widely used in Pharmaceutical industries or where <1 PPM TDS is required. EDI Doesn’t require chemical regeneration so, no need of shutting down the plant during regeneration. Thus, reducing the operation costs. Feedwater limiting conditions are strict in the case of EDI, so only RO or DM treated water must be used as feed water for EDI.
Features
- Consistent conductivity (<1us-cm)
- No chemical Regeneration required
- Low Operating Cost
- Can be sanitized
- Auto Dumping in case inlet conductivity exceeds
- Automatic/Semi-automatic operation.
- Sensors to monitor/ Safeguard the system.
Specifications

- Stable continuous performance with lower operating costs
Nano Filtration System
Nano filtration is applied to remove multivalent ions (like heavy metals) and is often used for de-colorization, de-salting, and reducing the amount of organic matter. As a filtering technique, Nano filtration is situated in between ultra filtration and reverse osmosis. An ultra filtration will not separate ions, whereas NF will remove the larger ions. An RO, on the other hand, will remove nearly all the ions. NF has the same setup as an RO: a large stream flowing by the membrane while only the filtrate stream goes through the membrane. Nano filtration also works according to this cross-flow principle.
Features
- Low Operational costs.
- Automatic/Semi-automatic operation.
- Sensors to monitor/ Safeguard the system.
- Viruses, organic elements, and valence ions are removed from the hard water.
- It is an effective way of softening the hard water.
- The membrane has very tiny holes therefore, most molecules cannot pass through.
Specifications
- Tangent offers skid mounted systems with multiple options for Skid MOC, Make of components and level of automation.
Applications
- Polishing and quality enhancement of conventional water treatment
- water softening and hardness removal and removal of synthetic organic matter in water with low total dissolved solids
- NF membranes are also used for the removal of natural organic matter from water, especially tastes, odours and colours, and in the removal of trace herbicides from large water flows.
Filtration & ion exchange
Filtration
Filtration is a process that removes particles from suspension in water. Removal takes place by a number of mechanisms that include straining, flocculation, sedimentation and surface capture. Filters can be categorised by the main method of capture, i.e. exclusion of particles at the surface of the filter media i.e. straining, or deposition within the media i.e. in-depth filtration.
Ion-exchange
The ion-exchange process percolates water through spherical, porous bead resin materials (ion-exchange resins). Ions in the water are exchanged for other ions fixed to the beads. The two most common ion-exchange methods are softening and deionization. Softening is used primarily as a pretreatment method to reduce water hardness prior to reverse osmosis (RO) processing. The softeners contain beads that exchange two sodium ions for every calcium or magnesium ion removed from “softened” water.
Multi Grade Sand Filter
The Multi grade sand filter provided by Tangent consists of mesh of various graded (sized) media together. The media inside the filter is arranged in such a way that it produces a filter bed with adequate pore dimensions for retaining both large and small suspended particles. Raw water with 25 to 50 PPM Suspended solids, produce filtrate with less than 5 PPM on passing through the filter. It can be used stand alone to remove physical impurities in water or can be used as pretreatment to safeguard further equipment’s.
Features
- Effective for Suspended solids removal
