  • Soil health

    The vitality of healthy soil extends to all of us. When our soil maintains its health, it fosters optimal crop growth and minimizes plant disease challenges. A robust soil structure characterized by crumbliness, efficient drainage, and moisture retention is key. Through efforts directed at soil health, issues like compaction, flooding, drought, erosion, and compromised crop growth can be preemptively addressed. Furthermore, a healthy soil serves as a habitat for soil organisms, thereby contributing to overall biodiversity.

Recharging of groundwater

Artificial recharge involves increasing the rate of groundwater recharge significantly beyond the natural percolation rate. This method ensures that groundwater recharge meets the demand. In the country, there is a phenomenon where the annual groundwater yields during pre-monsoon or post-monsoon, or both, surpass the annual groundwater recharge. This imbalance has led to a noticeable decline in long-term groundwater levels.

IoT based water monitoring system

Various methods exist for monitoring water conditions. Experts in monitoring employ sampling techniques to assess the chemical state of water, sediments, and fish tissue. These assessments help in evaluating the levels of essential components like dissolved oxygen, nutrients, metals, oils, and pesticides.

We propose an IoT-based water monitoring system designed to measure water levels in real-time. Our prototype focuses on the significance of water levels as a crucial parameter, particularly in flood-prone areas. The system utilizes a water level sensor to detect the desired parameter, and when the water level reaches a specified threshold, the system sends real-time notifications to social networks such as Twitter. Additionally, a cloud server is configured as a data repository for storing the collected information.

Professionals involved in the management and operation of water, wastewater, and stormwater systems, including civil and environmental project engineers and project managers, can benefit from this resource. It offers a wealth of visual aids, such as pictures, diagrams, and graphs, to enhance understanding and provide valuable insights into these systems.

Ballasted Sedimentation (Flocculation)

Ballasted sedimentation, also known as ballasted flocculation, is a water treatment process that utilizes coagulation and flocculation with recycled media, typically sand, acting as ballast for suspended solids and flocs. By introducing sand into the process, suspended solids or micro-flocs can attach to the sand particles, causing them to settle out of suspension more rapidly compared to when sand is not present. This enhances the efficiency of sedimentation in water treatment applications.

Ballasted flocculation is a high-rate physical-chemical treatment process used in water treatment. The process involves several steps. Initially, raw water is introduced into a coagulant mix tank where coagulants are added. The coagulated water then overflows a weir and enters a flocculation tank.

Following the flocculation tank, the water continues its flow into a clarification tank as part of the ballasted flocculation process. In the clarification tank, the primary objective is to allow the settled solids to separate from the water, resulting in clean water. To enhance the settling rate and improve the efficiency of the clarification process, many ballasted flocculation clarifier tanks incorporate inclined tube or plate settlers. These settlers are designed to provide a larger settling surface area within a relatively small tank footprint.

Once the settling process is complete in the clarification tank of the ballasted flocculation system, the sludge that accumulates at the bottom of the tank needs to be further processed. To separate the micro-sand from the solids, the sludge is pumped into a hydrocyclone. In this case, the hydrocyclone is specifically used to separate the micro-sand from the solid particles present in the sludge.

High Compaction Clarifying Thickener

In the past, customers faced a dilemma when selecting a wastewater treatment option as they had to choose between a clarifier and a thickener. Clarifiers were capable of producing clean water suitable for reuse; however, the sludge discharge from clarifiers had a high water content, making it challenging to manage effectively. On the other hand, thickeners offered a more manageable sludge underflow, but the quality of the clarified water was not sufficiently clean for reuse purposes.

A High Compaction Clarifying Thickener is an advanced wastewater treatment system that offers significant water recovery and high solids concentration in the underflow. With this system, it is possible to recover up to 90% of the process water while discharging an underflow with a solids concentration of 65% or higher by weight. The design of these systems is vertically oriented, featuring cone bottoms, rotating rakes, and water pressure to achieve the desired results. The vertically oriented design allows for efficient settling and compaction of the sludge, maximizing the concentration of solids in the underflow.

Raw water enters the central well from the top of the tank. Coagulants and flocculants can be added as the raw water flows or as it flows through the pipes that carry the raw water to the top of the clarifier. The source of the water to which the raw water is supplied can increase effective flocculation. In addition, a good foundation decomposes the incoming energy and prevents the sedimentation process in the pool.

As the particles and flocs settle, they are compacted by the rotating rakes to form a dense sludge. In addition, the vertical formation method uses high water pressure to compress and dewater the bottom sludge. Compressed sludge is discharged from the container at the bottom of the tank and clean water flows through a dam.

Soil compaction, an underestimated problem

Soil compaction is emerging as a significant global concern. This issue isn't confined to a single location; rather, it's a worldwide phenomenon. Soil compaction refers to the degradation of soil structure due to compression. This pervasive problem is often underestimated and has far-reaching consequences for agriculture, ecosystems, and the climate. Additionally, soil compaction results in reduced yield, diminished quality, and decreased water retention capacity.
