Lake & Pond Cleaning

  1. 1. S Simple Solution for Lake Management
  2. 2. E P I L I M N I O N The topmost and warmest layer of water is known as the Epilimnion layer. This layer also contains the highest quantity of oxygen compared to the other parts of the lake. This layer mixes thoroughly withsurface winds and provides fluctuations in oxygen levels. The warm temperatures and higher oxygen makes this layer suitable for a majority of the flora and fauna species of fish.
  3. 3. M E T A L I M I O N The layer between the epilimnion and hypolimnion is called the Metalimion layer. This layer experiences a rapid reduction in temperature with depth (@ rate of 1 degree per meter). Since the density of water also changes with temperature, the water does not easily rise or sink in this layer. The metalimion layer is also known as the thermcline layer.
  4. 4. H Y P O L I M N I O N The hypolimnion layer is the lowest layer and is directly beneath the metalimnion layer. This water in this layer is much colder and dense. The stagnant waters of the hypolimnion layer are too deep to be significantly effected by surface winds and currents. Water that is remote from surface influences has a relatively small temperature gradient. In eutrophic lakes, this lower layer of water has no oxygen and is loaded with toxic and decaying materials. The bottom of the lake is known as the benthal.
  5. 5. E U T R O P H I C A T I O N Ponds or Lakes that support rapid algae or plant growth are termed “eutrophic” ponds. Eutrophication comes from the Greek work for “over fed” and that’s just what plants are when they tend to grow to fast. Such ponds are overly fertile with plant food (mainly nitrates and phosphates).
  6. 6. Lake Polutants
  7. 7. Dredging and de-silting – De-weeding/hyacinth control or removal (biological, chemical, mechanical and manual measures, bio-composting Bio-remediation (Clean up with bio- products - natural bacteria breakdown, and aerators to churn the lakes) Introduction of composite fish culture/larvivorous fish species to control mosquitoes
  8. 8. Out in the deeper, or limonitic part of the lake the plankton take over. Plankton is a term used to describe those organisms that float freely in the open waters of the lake. Included in this group are the zooplankton (animals) and phytoplankton (algae). Fish, of course, also roam around out here. In a more productive lake the area fish have to roam around gets smaller and smaller as summer progresses. Oxygen in the deeper waters becomes scarcer as dead algae and other detritus rains down into the hypo limnion. Most fish won't be able to survive in dissolved oxygen concentrations less than 5 mg/L.
  10. 10. Topography • Basin Area : 240 km2 • Direct Catchment Area : 67 km2 • Shoreline Length : 14 km • Maximum water spread Area : 5.7 km2 • Capacity : 27.18 million m3 • Average Depth : about 5m • Inflow Nallas : Picket Nalla, Banjara Nalla, • BalkapurNalla, and Kukatpally Nalla
  11. 11. Existing Problem Highly Toxic Abnormal Algae Bloom including Cyno bacteria Pungent Smell Bottom Slushy Presence of other contaminants viz: Heavy Metal, Salts, Bacteria etc.
  12. 12. What To Do Rehabilitating Preventing Sustaining
  13. 13. Flash Objective To Oxygenate & Oxidize To remove odor by way of de-odorizing products. To control the growth of Algae & Fungus. To remove bio fouling. To clarify the water column & Pond bottom.
  14. 14. Protocol -1 QUICK FIX PROGRAMME: To treat in combination with Triozon F, CLO2 & CuSO4. 6 Shock Doses & 32 Maintenance doses. To use high power chemical dosing pump with elongated pipe for treatment @1 meter above Pond bottom level. Floating Service to be Supported by Dept. Area of treatment to be spot decided subject to contaminant level.
  15. 15. Protocol-2 {Bottom Aeration} The installation of a pond bed aeration oxygenates the water at the bottom, and eliminates the hypolimnion by low cost, low powered, continuous destratifcation of the thermal layers. The whole idea of aeration is to get oxygen into the deep water. Aeration with tiny air bubbles from bottom up and circulation of lower water layers helps to achieve uniform levels of oxygen and temperatures throughout the lake. Once the lake or pond is full of oxygen near the bottom, new insect larvae, snails and other fish food can begin to live at the bottom.
  16. 16. PROTOCOL-3 {BIO-ENZYME} A good lake is one, which contains fresh; sparkling clear, sweet smelling water and which supports fish life free from excessive algae and weeds. Biotechnology based solutions involve the use of scientific methods to aintain the natural health of lake. The Essential components of a good Biological solution are: (A) The presence of a sufficient quantity of beneficial facultative bacteria (B) The provision for sufficient Pond/Lake Bed Aeration
  17. 17. Be-Aware Being Chemical dosing utmost care should be taken while handling the products. Egg Has to be handled like egg. Glass has to be handled like glass. Visible eruption of entrapped Algae will surface up, post treatment. Either this has to be remove manually, or flushed out thro outflow source. Public & Press has to be kept informed that State is in process of cleansing the lake, hence for couple of weeks this situation is inevitable for good.
