“…It is found that the amount of phosphate in the seawater is small compared with that of waste waters. This is probably due to the deposition and migration of phosphorus from overlying water to the sediment [16,45], the high rate of consumption at the surface layer by organisms [33], the slow rate of regeneration of phosphate from underlying sediment [33,35], and the influence of the distribution of phosphate within the surface layers of natural waters [44].…”

“…This owing to high effect land-based sources (i.e. sewage, agriculture, and/or industrial effluents) [16,26], the increase of regeneration rate of silicate from underlying sediments, the decomposition and death of diatom [35], and the low rate of the uptake of silicate by microorganisms especially diatoms. This is strongly supported by the low count of diatoms in Abu-Qir Bay [26,45].…”

“…The growing increase in Egyptian population, as well as urbanization expansion; lead to a corresponding increase in industrial, agriculture, urban effluents that discharged into the aquatic environment of Egypt [8][9][10][11][12][13][14][15], leading to water quality deterioration. Poor quality water can lead to water borne diseases as well as death of aquatic life [16][17][18][19][20][21][22].…”

Background: The growing increase in Egyptian population, as well as urbanization expansion; lead to a corresponding increase in industrial, agriculture, urban effluents that discharged into the aquatic environment of Egypt. Objective: This study was conducted to evaluate the alteration occurred in some water quality characteristics of different water bodies subjected to different types of pollutants. Methods: Different physicochemical parameters, nutrient salts, total dissolved copper, and total dissolved carbohydrate were measured according to advanced experimental methods and analytical techniques. Results: The results of the hydrochemical parameters revealed that the temperature ranges for Abu-Qir drain waste water and Abu-Qir Bay seawater were normal. The values of salinity for waste water and seawater were (0.19-0.43‰) and (30.2-32.2‰), respectively which are much lower than that of the Mediterranean seawater (38.50‰) due to the discharge of huge amounts of fresh waters into Abu-Qir Bay. The pH values varied from one drain to another according to the geographical position and the amount of waste waters discharged into the area. Dissolved oxygen for waste water and seawater are ranged from a complete depletion to 9.42 mg/l and from 4.53to 4.87mg/l, respectively. On the meantime the range values of oxidizable organic matter for waste water and seawater were 21.6-84.0mg/l and 14.4-42.4mg/l, respectively reflecting the high loads of organic matters added into Abu-Qir drain from different companies. On the other hand, the range values of ammonia varied between 10.20 and 95.6µM for waste water and between 7.50 and 10.10µM for seawater; respectively leading to eutrophication problems in the Bay. The nitrite for waste water and seawater were 2.60-32.40µM and 5.33-6.30µM, respectively, while the range values of nitrate for waste water and seawater were 0.74-36.74µM and 3.51-13.51µM; respectively. The range values of phosphate for waste water were 3.36-21.36µM, while it was 1.30-11.62µM for seawater. It is found that the amount of phosphate in the seawater is small compared to that of waste waters. Generally speaking, the waste and seawaters of the investigated area exhibited high silicate concentrations. Dissolved copper concentrations in Abu-Qir drain and Abu-Qir Bay ranged from 2.80 to 11.58µg/l and from 4.80 to 5.68µg/l; respectively. The range values of TDCHO for wastewater was 0.16-0.92µg/l and for seawater was 0.77-3.15µg/l. Conclusion: It is concluded from factor analysis (FA) that the investigated hydrochemical parameters are the major controlling factors in the distribution patterns of copper and TDCHO in both Abu-Qir drain and Abu-Qir Bay affecting seriously their water quality.

“…The dynamics of water masses and circulation in El-Mex Bay control the accumulation, distribution, and flux of wastewater (Alam El-Din, 2001; Farag, 2009), which are in turn affected by the continuous alteration in the morphology of the bay due the extensive constructions of new infrastructures. Shreadah et al, 2014;2015a), the winter-closure period (in January and February) leads to accumulation of pollutants in the drain, and the wastewater in the canals is subjected to strong unsteady flow, while a relatively stable flow occurs from June to October.…”

“…The pond of oxidation has attempted to be one of the most important affordable waste treatment methods for small isolated industrial and community units in African country (Mahajan et al, 2009). The existence of bacterial species is more (Kogo et al, 2017), beside to the diversity of fungi-classification (Masoud et al, 2016), and algal-classification (Shreadah et al, 2015;Henry et al, 1987), in addition to protozoa-classification (Abd-Elhamied, 2020;Tembhre & Kumar, 1997), and virus-classification (Shaltout et al, 2019). The microbiological solids produced by the algae on the pond impact total suspended solids (TSS) and biochemical oxygen demand (BOD) in effluent (Tuleibah et al, 2015).…”

People who are involved in managing wastewater treatment face the challenge of achieving conservation goals with limited funds, and also of balancing needs for nature conservation. This context has been motivated with finding logic explanations of wastewater treatment by oxidation ponds. Description of progressive we have made with developing methods is for understanding how, when and where had done to apply the oxidation ponds for protecting biodiversity. The Rashid oxidation pond facility was highlighted as a model plant for utilizing this technology in wastewater treatment in the city of Rashid, El-Beheira Governorate, Egypt. The main concept is based on the interaction of chemical pollutants NO 2 , NO 3 , BOD 5 -in, and BOD 5 -out and heavy metals with microorganisms as Chlorophyta Green and cyanophyta, and how these oxidation ponds imitate the Continuous Chemical Reactor (CSTR) to build its core architecture for maximum usefulness. By applying the theoretical equation of (CSTR) on the experimental results of the oxidation pond according to Thirumurthi equation, it was discovered that (CSTR) and oxidation pond are matching together with a satisfactory ratio of congruence (85% -88%). Also, the heavy metals as (iron, Zinc and copper) are high percentage removal by the algae rules. This investigation established that the oxidation ponds may function as a Continuous Chemical Reactor under ultimate conditions and precautions.
